Introduction of soil NPK sensor

User:JXCTUpload time:Jan 05 2022

Soil NPK sensor is mainly used to detect the content of nitrogen, phosphorus and potassium in soil environment.

It helps determine soil fertility and thus facilitates systematic assessment of soil condition.

Sensors can be buried in the soil for a long time. It has high quality probe, rust resistance, electrolytic resistance, salt-alkali corrosion resistance, to ensure the probe part of the long-term operation.

Therefore, it is suitable for all kinds of soils. Suitable for testing alkaline soil, acid soil, basal soil, seedbed soil and coconut bran soil.

The sensor does not require any chemical reagents. It can be used in any microcontroller because of its high measuring accuracy, fast response speed and good interchangeability.

Because the soil NPK sensor has a Modbus communication port, the sensor cannot be used directly with the microcontroller. Therefore, you need any Modbus module (such as RS485) and connect the sensor to the microcontroller.
